DECISION GUIDE
When to pick each, and when to skip both.
Three plain-English paths: the case for Sentry, the case for SigNoz, and the free bring-your-own-key route that avoids seat fees entirely.
When to Pick Sentry
98.7 / 100- 45,615+ GitHub stars as the definitive standard for application exception tracking and release health
- Automatic JavaScript, Python, and mobile source map demangling with visual stack trace navigation
- Rich breadcrumb timeline recording user actions, network requests, and console logs leading to crashes
When to Pick SigNoz
98.5 / 100- 32,408+ GitHub stars under Apache-2.0 built natively on OpenTelemetry standards with zero proprietary vendor agents
- Unified APM dashboard correlating distributed request traces, service dependency graphs, and host metrics
- ClickHouse columnar storage delivers sub-50ms p95 query speeds across billions of spans at 92% lower cost
When to Self-Host in Docker / K8s
Docker / Helm HA- $0 SaaS Usage / Per-Node Tax: Run on $18-$45/mo cloud VMs or bare-metal Kubernetes nodes with flat, predictable monthly compute.
- 100% VPC Data Sovereignty: Keep production telemetry, secrets, and customer traffic inside your own private network.
- Production HA Spec Included: Deploy with pre-tuned
otel-collector.prod.yaml+helm-values.prod.yamlhealthchecks and resource limits.
